Solitary fibrous tumor of the breast: A case report and review of the literature

Solitary fibrous tumor (SFT) is an uncommon neoplasm of mesenchymal origin, which can be benign or malignant. Most SFTs develop from the pleura, but they can also be found in other sites. There are only few reports of SFT occurring in the breast. We herein report such a rare case. Sonography demonstrated an ovoid lesion mimicking a fibroadenoma, whereas color Doppler imaging showed marked internal vascularity. A brief literature review on imaging features of SFTs is added. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:350-354, 2017.
